Intrusion detecting method of internet-of-things sensing layer

The invention discloses an intrusion detecting method of an internet-of-things sensing layer, and relates to a safe detecting method of the internet-of-things sensing layer, in particular to a detecting method for judging whether intrusion behaviors exist in the internet of things by combining the feature detection technique and the abnormal detection technique. In order to solve the problems that the false alarm rate and the omission rate are high and the detection rate is low in the prior art, the method is used for performing intrusion detecting by combining the feature detection technique and the abnormal detection technique. Compared with the prior art, the method has the advantages of being low in false alarm rate and the omission rate, high in detection rate, good in timeliness and the like, and is suitable for the intrusion detection of abnormal behaviors of the internet-of-things sensing layer.
